Speeication forming p art of Letters Patent Ilo. 130,0399 dated July 30,1872.

To whom it may concern:

Be it known that I, J oNA'rI-IAN HALEY, of

the borough of Allentown, Allegheny county,

accurately into the center of the mold or artiate on the moldslide upand down in continuous bearings or Ways, provided each with a gib-plateextending nthe length of the bearing, so arranged that it may be se't upor adjusted to takeup any Wear of the `parts which may occur; and I alsomake the bearing portions of the said movable parts which are in contactwith the slides or` Ways and gib-plates of such lengthas to obtainelongated bearingsuri'aces, and prevent any undue Wearing of saidslides. l

i In order to prevent jarring or jolting of the parts during theirmovement, I combine with them and the connecting-rods by which they areactuated from the crank-shaft, crank-pins so constructed that they maybe at any time tightened up and adjusted to take up any loose motion,and yet in no Way interfere Withl `or `prevent the movable parts whichoperate directly on the mold from working perpendicularly. i

In the accompanying drawing I have represented so much ofa glass-pressas is needed to illustrate the manner in'Which my invention is or may becarried into effect.

Figure 1 is a perspective view of the press. Fig. 2 is a like view ofthe movable parts which operate directly on the mold detached from thepress. Fig. 3 is a horizontal section To this end I so construct" .the`press that the movable parts which operon an enlarged scale through thepillars of thc press. Fig. 4 is a section on au enlarged scale throughthe lower end of one of the connecting-rods, showin g the constructionof the crank-pin. 1

The press, except in the particulars specified,

is of ordinary or suitable construction, and l shall, therefore, confinemy description to those parts immediately A connected With theseimprovements. i

A is thc bed-plate, upon which the mold is supported. B is the springplate; C, the crosshead; D, the yoke; and E, the adjustable plunger-rod.The general arrangement and construction of these parts, constitutingthe movable parts which operate directly on the mold, is similar to thatof like parts in glasspresses in general use, and require no furtherdescription. The parts B C D slide in pillars or posts F, in which Waysor grooves a are formed for the reception of the ends or bearings ofthese parts. For the purpose above mentioned, I place in each of theWays or slides a a gib-plate, b, extending the length of the bearings,provided preferably with a tapering iin, c, on the face contiguous tothe moving parts B C D, a groove of corresponding shape being formed inthe ends of these parts to receive the fin or rib. Each gib-plate iscombined with screws or equivalent devices, d e, placed at intervalsapart throughout the length of .the pillars, and arranged as shown. Thegib-plates are held in place by screws c, and are set up against thebearings of the parts B O D by the 'screws d. By means' of theseset-screws and holding-screws the gib-plates can be adjusted to take upany Wear, and to cause the moving parts to slide up and downV in avertical plane and With perfect accuracy, v

Without any swinging or untrue motion. The bearing parts of the yoke,cross-head, and spring-plate are made of such length, as shown at l 2 3in Fig. 2, as to prevent any undue Wear upon the slides or Ways of thepillars, thus further insuring the accuracy of movement of these parts.The. moving parts B C D are actuated to slide up and down by means ofconnecting-rods G, one on each side of the machine, jointed at theirupperend to the yoke D, and mounted at their lower end upon Wristpinsot' cranks g on the shaft H, which shaft is operated by a lever, I, inthe usual way. In ordinary glass-presses there is considerable wear atthe point where the connectingrods connect with the wrist-pins, and whenthis wear takes place there results a jar or `iolting motion, which isextremely objectionable and prevents the accurate working of the press.I therefore construct and combine together the connecting-rods andWrist-pins, so that any looseness of parts resulting from wear or othercause may at once be taken up. Each crank-pin h, nearest the point whereit is connected with its crank g, is formed with a conical or beveledportion, i, the base or largest part being ne'Xt to the crank-arm. Theother and outer portion o the pin is made cylindrical or of the samesize throughout. Upon the piu I place a washer, j, of conical form orbeveled to correspond with the bevel of the part t of the piu, but withits largest part outward, and between the two beveled parts z' and j Imount on the pin several thin washers, k, of metal or other material.These thin washers, as Well as the washer j, slide freely on thecrank-pin. The lower end of the connecting-rod Gr has a hole formed init to encircle the crank-pin, and this hole is beveled on each side fromthe center to fit upon and correspond with the oppositely-inclined orbeveled surfaces of the parts t' and j. The washer .j is set up by meansof a nut, l, screwing on the end of the crank-pin, so that the joint maybe made perfectly tight and all rattle, jar, or jolting prevented atthat point. In case of any wear, one or more of the thin washers 7cmaybe removed, as required by circumstances, and the beveled washer jcan then be set up closer to the part t' so as to take up any Wear orlooseness of parts.

The absolute necessity of having` the movement of the parts whichoperate on the mold perfectly true and straight, Without any jar orjolting, renders these improvements, as applied to glass-presses, ofvery great value, While the parts, when necessity arises, can berepaired With the utmost facility, and with much greater economy ofmoney and time than is practicable in repairing glass-presses of theusual construction.

Having now described my invention and the manner in which the same is ormay be carried into effect, what I claim, and desire to secure byLetters Patent, is-

1. In presses for molding glass-ware, the combination, with the movingparts which operate upon the mold and the slides or ways in which thcbearing portions of said parts move and are guided, of gib-plates adjListed and held in said slides or ways, and operating in connection withthe bearings of said moving parts as and for the purposes herein shown.
